Abstract
A method of compensating image data, the method includes generating a compensation data of an image data in accordance with a temperature value by using a compensation data of a previous frame and a compensation data generated through a look-up table which is mapped with corresponding to a compensation data of a previous frame and a set temperature value which is smaller than and closest to the temperature value or which is greater than and closest to the temperature value among set temperature values.
